It depends on you. Some people get therapeutic benefit from regular psychedelic experiences, and never stop. Other people gain life-changing insights from one or several trips. Still others use/abuse it purely for fun, with a range of consequences resulting. A minority of people have adverse reactions where latent mental illnesses like schizophrenia can be triggered.

I'm in the second camp. A couple quotes that I relate to: "Once you get the message, hang up the phone" -- Alan Watts. "Never point [psychedelics] at anything you don't want perforated with new light"-- Terence McKenna.
